I am trying to load a view simply with a tableview. And when i pull the rows down i need to
display a search bar on top of first cell of table view. Every time this search bar should
appear only on pulling down the table view.
I tried this code in viewDidAppear: but it dint worked for me.
self.tableView.contentOffset = CGPointMake(0, SEARCH_BAR_HEIGHT);

You try with custom cell and then put a 3 views over there or taken directly UIImageView and Two UILabel. It is More easy.
I have a tableView with custom table cells which displays a list of sayings. While selecting a cell (say "saying1") from the tableView, the cell will get selected and will moves to next view controller for showing an explanation of selected saying. In that view controller two buttons "Previous" and "Next" are there for navigating to previous and next saying. So user may select next button for seeing next saying (say "saying2"). But the problem here is, In this stage when i navigate back to my tableview, the cell selected will be "saying1" not "saying2".
In order to solve this problem, i collected the currently selected sayings ("saying2's") index from array (ie,index will be 1) and passed it to the previous tableView through segue and converted that value into NSIndexpath. After this step i don't know what to do. Please help me in solving this.
You can specifically select a cell by calling following method present in UITableView class :
selectRowAtIndexPath:animated:scrollPosition:
refere to following link : https://developer.apple.com/library/ios/documentation/uikit/reference/UITableView_Class/Reference/Reference.html#//apple_ref/occ/instm/UITableView/selectRowAtIndexPath:animated:scrollPosition:
i have table view(it has sections). at a time it will show only 4 images/rows(the height of table View is set according to that). when the scrolling is done, it will display 5th row half section,6th row full, 7th row full ,8th row full , 9th row half section as usual. however i don't want to show the half section of any rows. i need to show the complete sections of rows in my table view(it may be Rows 5,6,7,8 or Rows 6,7,8,9) after my scroll function is done. is any way to do it?any property for tableView to do it?
I think you should combine next methods:
scrollToRowAtIndexPath:atScrollPosition:animated:
Scrolls the receiver until a row identified by index path is at a particular location on the screen.
- (void)scrollToRowAtIndexPath:(NSIndexPath *)indexPath atScrollPosition:(UITableViewScrollPosition)scrollPosition animated:(BOOL)animated
scrollViewDidEndDragging:willDecelerate:
Tells the delegate when dragging ended in the scroll view.
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
scrollViewDidEndDecelerating:
Tells the delegate that the scroll view has ended decelerating the scrolling movement.
- (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView
I have a table view which has full of items getting from my database. I open my app. I tap one of my items in table view, then DetailViewController that has only text field does not display anything it is empty. But when I go back to table view then tap any other item again , at this time it displays value what I wanted to display.. It does it for my only first tap.. I have no errors and warnings.. What am i missing?
Sounds like you implemented tableView:didDeselectRowAtIndexPath: instead of tableView:didSelectRowAtIndexPath:.
when I scroll position end of UItableview the last UItableview row seems half. how can I show the last row fully and how can I detect scroll to last row?
I don't know what you mean by "seems half". I suppose that means only half of the cell is shown? Make sure the frame of the whole table view is visible first.
If you want a cell to appear within the bounds of the table view, use
[tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:? section:?]
atScrollPosition:UITableViewScrollPositionBottom animated:YES];
I think there is something (like a tabBar) at the bottom of your screen and it is overlapping the UITableView .. am I right, am I right?!
Just make the frame of the UITableView 48 pixels shorter. That's the average size of a tabBar..
Or perhaps you have not taken in account that the bar at the top (the status bar) also counts, which is about 15 pixels high. In that case, take 15 pixels of the height of your UITableView's frame.
